We've got another problem pop up since we updated to Patch 7.1.4_P1.
We use nginx as a reverse proxy in front of our zimbra service to provide multiple ssl hosts, so webmail is actually on port 8888.
When I (as user 'admin') use the "View mail" button it works fine and connects to http://zimbra.example:8888, but when delegated admins try it, it attempts to connect http://zimbra.example:7070, which fails for fairly obvious reasons.
Where does this 7070 port come from and how can I stop that? This was working fine before I upgraded.
